MIT/GNU Scheme

MIT/GNU Scheme is an implementation of the Scheme programming
language, providing an interpreter, compiler, source-code debugger,
integrated Emacs-like editor, and a large runtime library. MIT/GNU
Scheme is best suited to programming large applications with a rapid
development cycle.

Release status and future plans

The releases provide binaries that run on i386 and x86-64 machines
under the following operating systems: GNU/Linux, OS X, and Windows.
We additionally provide binaries for selected other architectures and
systems, depending on the hardware and software that is available to
us. We no longer support OS/2, DOS, or Windows systems prior to XP.

In the future, we plan to deploy a new portable virtual machine and
implement a module system. We also plan to finish support for
R5RS and R7RS, but we will not be providing
support for R6RS.
Other potential projects can be found on the
tasks page.

Download

MIT/GNU Scheme is available in binary form for a variety of
systems.
Note that most problems unpacking or installing this software are due
to corrupted downloads, so please check the downloaded file
for a correct MD5 checksum before submitting a bug report.
Each distribution below has its own list of MD5 checksums.

Note that you cannot build a working system from the source unless you
have a working MIT/GNU Scheme compiler to do the compilation.
(This doesn't apply to the portable C source, which requires only a C
compiler.) This means that if the above binaries don't work on your
system, it is pointless to try building a custom set of binaries from
the source code.

Getting involved

Development of MIT/GNU Scheme, and GNU in general, is
a volunteer effort, and you can contribute. For information, please
read How to help GNU. If you'd like to get
involved, it's a good idea to join the discussion mailing list (see
above).

Development

For development sources, bug and patch trackers, and other
information, please see the
